What lutejones linked is a great introductory video on microbeveling and/or "steeling"/honing/burnishing, by using high angle ( 20-30 degrees per side ), doing that will straighten any rolls , and also sharpen the apex, basically you'll see results real fast, but after a few sharpenings,, you'll have to do more
So start with instinctive sharpening, try it at least three times, before watching a second video.
This would be the follow up video (actually video after that), try it with your std. dry stone (I just bought another one at dollar tree the other day )

Extreme low grit sharpening : clay brick - Cliff Stamp
Thats almost all the secrets of sharpening freehand right there, easily get to shaving sharp with that info, and if you use a light touch, whittle hairs.
After you've sharpened a dozen times, watch the videos again, ... a lot of info you won't really appreciate until you try sharpening, don't watch too many videos before practicing
To keep from changing the outline/profile, just follow the curve , pivot/rotate the blade to keep the edge at right angle(90 degrees) to the abrasive and end with the tip on the abrasive, don't come off the stone
